The AMIS-42665 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus and may be used in both 12 V and 24 V systems. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller.
The AMIS-42665 is a new addition to the CAN high-speed transceiver family and offers the following additional features:
= Ideal passive behavior when supply voltage is removed
= Wake-up (WU) over bus
= Extremely low current standby mode
Due to the wide common-mode voltage range of the receiver inputs, the AMIS-42665 is able to reach outstanding levels of electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the output signals.

• Compatible with the ISO 11898 standard (ISO 11898-2, ISO 11898-5 and SAE J2284)
• High speed (up to 1Mbaud)
• Ideally suited for 12V and 24V industrial and automotive applications
• Extremely low current standby mode with wake-up via the bus
• Low EME common-mode choke is no longer required
• Differential receiver with wide common-mode range (+/- 35V) for high EMS
• Voltage source via VSPLIT pin for stabilizing the recessive bus level (further EMC improvement)
• No disturbance of the bus lines with an un-powered node
• Transmit data (TxD) dominant time-out function
• Thermal protection
• Bus pins protected against transients in an automotive environment
• Power down mode in which the transmitter is disabled
• Bus and VSPLIT pins short circuit proof to supply voltage and ground
• Logic level inputs compatible with 3.3V devices
